Thermite By Jack Rjeili

What is Thermite?  Mix of aluminum powder and iron oxide [1]  Once ignited, produces extreme temperatures  Produced from union of aluminum and oxygen in oxide [2] Thermite Powder [A]

Uses of Thermite?  Burns at temperatures of approx. 2500°C (4532°F) [3]  Used for wielding/ cutting through metals  Most often used on train tracks  Tracks don’t need to be removed  No need for heavy machinery [4]  Used to purify metals  Aluninothermic Reaction [4] Thermite Wielding [B]

How Thermites Made Materials:  Iron Oxide (rust)- Fine powder  Aluminum powder  Magnesium ribbon- to light thermite [3]  Flowerpot- to contain burning thermite [3] Aluminum Powder [C] Magnesium Ribbon [D]

How Thermites Made  8 to 3 weight ratio of iron oxide to aluminum powder [3]  Mix very thoroughly  Pour mixture into container  Stick in magnesium ribbon and slightly fray end [3] Unmixed Thermite [A]
